Induction motor drive predictive direct torque control method

The paper deals with development of the induction motor drive direct torque control (DTC) based on the next step voltage vector prediction. The principle of the method is explained and the system mathematical description is provided. The derived control algorithm is implemented both in the simulation software MatLab/Simulink and on the real induction motor drive with dSPACE control system. Simulated and measured results in steady states and transients are presented.
